A knotless interference or contact fixation anchor assembly comprising an anchor body with a removable inserter/driver that fully supports the suture anchor over its entire working length. The anchor body may also incorporating a suture trap that is housed within a proximal eyelet of the anchor body. The anchor body may include a plurality of elongate ribs extending longitudinally along at least a portion of the anchor body. The plurality of ribs comprise flexible barbs. When inserted into bone or a bone tunnel, the barbs compress slightly, resulting in less bone compression around the anchor due to the forces required for insertion, and increased pull-out resistance.
